Distribution and habitat: — Brazil (Minas Gerais, restricted to the Diamantina region southwards to the Serra da Piedade near Ouro Preto). Campo rupestre; 800–1100 m.

Taxonomic notes: —A rarely collected species. Easily recognized by its adaxial greenish oblanceolate, elliptic to lanceolate leaves and 15–25-flowered capitula. Similar to Piptolepis gardneri : see that species for a discussion of the differences. Synonymy is based on the study of recent collections of that species which shows a great variation in the leaf shape and the number of florets per capitulum. Gardner probably collected materials of Vernonia burchelliana and V. martiana at the same locality under the same number (4754) and only later set apart both sets, indicating the V. martiana ’s collection by 4754/2. Both collections appear under the number 4754 in Gardner (1846).
